Both horn applicators and a cylindrical waveguide exposure system were used to radiate the animals. The CM frequency and duration were ATTACHMENT : similar irrespective of carrier frequency and mode of application. Parameters of the CM (except amplitude) were not influenced by orientation of the body axis to the electrical field or by pulse width of microwaves for pulses less than 30 microsec wide. The frequency of the CM correlated well with the longest dimension of the brain cavity and poorly with several dimensions of the head. Extrapolations of these animal findings to the human being indicates that the frequency of the microwave-induced CM in man should be between 7 and 10 kHz.

Medical Center, Kansas City) Clarke, Rex L.; <Dept. of Psychol ogy Univ, of Kansas, Lawrence) Keywords: microwaves, Abstract: Rats assayed by the technique of conditional suppression were able to detect the presence of 12.25-c.entime ter microwaves at doses of power approximating 0.5 to 6.4 milliwatts per gram. The assay, which controlled for sensitization, for pseudo and temporal conditioning, and for several possible ATTACHMENT : sources of artifactual cueing, revealed that irradiation by microwaves, although lacking the saliency of an auditory stimulus, can function as a highly reliable cue. Efficiency of detection was strongly and positively related to the amount of microwave energy to which the rats were exposed.

Title: Field measurements, absorbed dose, and biologic dosimetry of microwaves Source: Annals of the New York Academy of Sciences, Vol. 247, pp. 499-509, February 28, 1975.

Methods of dosimetry and ways of expressing radiation dose have been equally diverse. Without a common dose unit, it has been very difficult, if not impossible in ATTACHMENT : many cases, to compare the biologic effects produced with different exposure arrangements. There is an obvious need to establish a uniform method of expressing radiation dose if we are to be able to compare results between studies.
